Joint caretaker manager Scott Young says Cardiff City's 3-0 home defeat by Bournemouth in the Capital One Cup was unacceptable.
Dan Gosling scored either side of Charlie Daniels' left-footed drive to secure Bournemouth's place in the fourth round.
Defeat marked another low for managerless Cardiff, who have won just two Championship games and sit in 17th.
"That's not good enough for Cardiff City Football Club," said Young.
Former Bluebirds centre-half Young and player-coach Danny Gabbidon were placed in temporary charge following the departure of manager Ole Gunnar Solskjaer.
Wales defender Gabbidon was one of eight changes for Cardiff, making his first Bluebirds appearance in nine years.
But it was a miserable evening for the veteran and Young, who added: "That first 30 minutes performance is nowhere near the standard we set at this football club."
"I said to the players that the core values of this club when you pull that shirt on is determination, desire, work rate and everything like that.
"That's what they need to realise. They're paid to play for this football club.
"You need to have desire to play football. If you haven't got desire, hard work and commitment then there's no point being out there."
Cardiff, who host Sheffield Wednesday in the Championship on Saturday, are still interested in talking to Leyton Orient boss Russell Slade about their vacant managerial post.
Orient rejected an approach for 53-year-old Slade, who has been their manager since 2010, while Young said he would be happy to remain in charge for the time being.
"I'm sure we'll sit down with the chairman and the chief executive and see where it takes us," said Young.
"I definitely want to be in charge for Saturday because we need to rectify that.
"The result hurt me - this is my football club. I want to put that right."
